CUSHIONING SUPPORT.

Application tiled April 12, 1920. Serial No. 373,181.

To all Iwhom z't may concern.

Be it known that I, JAMES EDWARD CassIDY, a citizen of the UnitedStates, residing at Washington, District of Columbia,

54 have invented new and useful Improvements in Cushioning Sup orts, ofwhich the following is a full, c ear, concise, and 'exact description,reference being had to the accompanying drawing, forming a part of thisspecification.

My invention relates to sound-deadening means, and it has particularrelation to means of the character designated embodying cushionsupporting members which are adapted to engage structural sustainingmembers whereby thesound vibrations gen-` erated in one portion of abuilding are pre-I cluded ifrom travelling through a supporting floor orpartition into another portion of said building byreason of thecontinuous physical contact of the structural sustaining membersemployed.

For a better understanding of my invention reference may be had t'o ,theaccompanying drawing, in which;

Fig. 1 is an elevational sectional view showing my improved sounddeadening means embodied in a floor structure;

Figs. 2, 3 and 4 are elevational views of modified cushioning meansconstructed in accordance with my invention, Fig. 2 bein an endsectional elevational view througlgi ia porction of the structureillustrated in Fig.

,an Fig. 5 is an enlarged perspective view of the manner in which thecushioning means employed in my invention are disposed in one embodimentthereof.

I have discovered that in order to obtain satisfactory sound insulationit is necessary to eliminate all continuous physical contact Y betweensound absorbing mediums. Moreovcr, while eii'orts have heretofore beenmade to obtain a sound insulation through the employment of onecushionin device this does not give satisfactory resu ts. Experimentshave proved that, when but one cushioning device is interposed between aortion of a buildin in which sound virations are generate 'and anotherportion thereof, from which it is desired to exclude said' vibrations,some of the latter will in-v variably, asr expressed Ain the art, leakthrough. v

ticular construction of the cushioning4 means, as well as by the ymannerof placing the same, as will be hereinafter ointed out.

These means are so constructe that a plurality of cushioning members arecompactly embodied in one device, and moreover, the

cushioning members are so disposed that A the device may be interposedbetween two sound absorbing mediums with a minimum consumption of spaceand withpthe greatest simplicity of installation.

Referring now more particularly tothe drawings and considering Figs. 1,4 and 5, a cushioning device 10comprising two opposed U-shaped members11 and 12 is shown. The members 11 and 12, in the figures referred to,are secured in back-to-back relation and the arm portions thereof aredisposed at right-angles to each other.

Arranged within the IUvsha ed members 11 and 12 'are pads 13 which a ordcushionsupv orts for structural-sustainin members,

as s own. In Figs. 1 and 2, suc members` areshown at 14 and 15, theformer com-v prising a Stringer to which is secured floor- 1ng 16. TheStringer 15, on the other hand, is secured between the padded portion 11of the device 10 and a padded portion 17 of another and differentlyconstituted cushioning device 18, the latter bein provided with asupportingv means 19 whic is in turn secured to a rough oorin 20. [Itwill be observed that the rough In Fig. 3, I have illustrated the mannerin which two of myy improved devicesmay ooring is secured vin aconventional manner to beams 21.

be interposed between two sound-absorbing mediums.A Here the bottom ofthe'stringer 15 is positioned in the same kind of equitant cushioningdevice as is used at the top thereof. The downwardly extending equitantportion of the lower cushioning devicey v straddles a Stringer 22 whichis in turn slecured to flooring or ceiling 23.

In connection with the embodiment of iny invention just described, itwill be observed that by using two ofthe cushioned-members in the mannershown a very compact sounddeadening construction may be realized.

An even more compact structure is illus'- trated in Fig. 4 wherein theStringer 15 lis se- 'cured directly to a ceiling or floor portion 24. Itwill be observed that the same manner of mounting the equitant portionsis illustrated in 4the enlarged view of the Fig. 5. This, however, ismerely illustrative and it is obvious that the equitant portions may besecured in back-to-back relation in such manner that the arm portionsthereof are in the same plane. I find, however, that the aboveillustrated embodiment results in an especially compact and simplesounddeadening construction.

It will be observed from the above description that I have provided aconstruction in which a plurality of cushioning pads are employedwhereby those vibrations,

which leak through the first sound-insu lating cushions, are absorbed,and it will, moreover be observed that by the particular arrangement ofthe equitant, pad-retaining members, which I have illustrated, I amenabled to interpose the required number of devices between twosound-absorbin mediums with a minimum consumption o space.

While I have illustrated a plurality of embodiments of my invention itis apparent that many modications therein may occur to those skilled inthe art, I desire, therefore, that my invention be limited only by thescope of the prior art or by the statements of the appended claims.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

l. Sound-deadening means comprising a cushioning support embodyingopposed members.

2. Sound-deadening means comprising a cushioning support embodyingopposed U- shaped pieces having supporting pads dapted to engagefloor-sustaining memers. 3. Sound-deadening means comprising opposedcushion-supporting members provided with base ortions and arms extendingtherefrom w ereby structural sustaining members on opposite sides ofsaid means are afforded padded seats.

4. Sound-deadening means comprising opposed cushion-supporting membersadapted for equitant engagement with structuralsustaining members. y

5. Sound-deadening means embodying lgpposed equitant, cushion-supportingmemers.

6. Sound-deadening means embodying opposed equitant, cushion-supportingmembers, the arm portions thereof being arranged at right angles to eachother.

7. Sound-deadening means embodying opposed equitant members providedwith cushion linings, said members being arranged in back-to-backrelation to aord padded seats for structural supporting members onopposite sides of said means.

8. Sound-deadening means embodying opposed equitant members providedwith cushion linings, said members being arranged in back-to-backrelation to afford padded seats for angularly-disposed structuralsupporting members on opposite sides of said means.

In witness whereof, I have hereunto subscribed my name.

JAMES EDWARD CASSIDY.
